Question

What is the solubility of sodium chloride in 20 °C water?

Answer 1

Answer:

The solubility of sodium chloride is, then, 35.7 g/100 mL water at 20°C. Sodium chloride is a moderately soluble salt. The solubility of sodium nitrate is 92.1 g/100 mL water at 20°C; sodium nitrate is a very soluble salt.

Answer 2

• At 20°C, the solubility of sodium chloride (NaCl) in water is about 36 grams per 100 milliliters of water, or about 26.4% by weight. This means that at this temperature, 100 milliliters of water can dissolve about 36 grams of NaCl before reaching saturation.
  
  Sodium chloride, also known as table salt, is a very common and important compound that is soluble in water. The solubility of sodium chloride in water varies with temperature. As the temperature of water increases, its ability to dissolve NaCl also increases, meaning more salt can dissolve in warmer water.

• At 20°C, the solubility of NaCl is approximately 36 grams per 100 milliliters of water. This value is referred to as the saturation point, which means that the water has reached its maximum capacity to dissolve NaCl at this temperature. If more salt is added to the water at this point, it will not dissolve and will instead form a precipitate at the bottom of the container.

• It is worth noting that the solubility of NaCl can also be affected by other factors such as pressure and the presence of other substances in the water. For example, adding other salts or ions to the water can affect the solubility of NaCl, either by increasing or decreasing it. Additionally, changes in pressure can also affect the solubility of NaCl, although this effect is relatively small compared to temperature and the presence of other substances.

• Overall, the solubility of NaCl in water is an important property to understand, as it has implications in various fields such as chemistry, biology, and food science.
